Do-It-Yourself Health: Fitness Challenge, Week 4

Week 4. Give yourself a pat on the back if you’ve made it this far. And speaking of your back, this week’s stretches are designed to help prevent common lower-back pain. They’ll also help strengthen your core.

Try mixing these back-healthy exercises in with the strength-building circuit from Week 1 and Week 3, and any of the stretches from Week 2. Remember, for exercises requiring repeated movements, try to do 15 reps per set.
